Since D is now looking to push out a storyline post-haste
and the kraken I don't think is ready yet - I wouldn't expect to see it with the upcoming storyline (and its not mentioned with Rott's Crew in chat or in any recent Disney story releases...)
Not to say I'll be missing him - if it means we get a second quest soon without him he can come along later
Once he does arrive though - we already have Cannon Shot for it so it is ready to go
